Modeling of non-utility facility with generation and battery storage is presented. The operation strategy for non-utility facility is determined by solving a daily generation scheduling problem under a price-taking scheme. Numerical simulations are performed under various scenarios. It is shown that the optimal strategy is complex when either fuel supply is limited or electric utility allows buy-back...
In modern world, every industries including the power industry address technological changes. Therefore, it is necessary to keep track of international experiences and activities taking place in every field. This paper provides an overview of the concept of Unit Commitment (UC) problem with a bibliographical survey of relevant background, the present state and potential methodologies used for solving...
An offshore power transmission grid in Northern Europe has become a serious and important topic among the power industry, the power transmission sector, national governments and the European Commission. The OffshoreGrid project will provide policy recommendations for the political process towards such a grid in pursuing the efficient integration of renewables, the integration of market regions, security...
Plug-in hybrid vehicles (PHEVs) and Plug-in Electric Vehicles (PEV) are promoted in many jurisdictions worldwide as a way of reducing reliance on fossil fuels and reducing green house gases. In Canada, most utilities have initiatives in this area, with the aim to assess the impact on their electric grid of the wide scale deployment of these vehicles. There is also a significant interest on the part...
The past decade has seen a dramatic change in the manner in which the power industry is organized. It has moved from a formerly vertically integrated and highly regulated industry to one that has been horizontally integrated in which the generation, transmission and distribution are unbundled. In a deregulated environment, Congestion in the transmission lines can be relieved by one of the two congestion...
This paper applies two methods to evaluate the economic effects of the policy of "replacing small units with large ones (RSWL)," one is Discounted Cash Flow (DCF) method which performs a technology economic analysis both from the financial and the economic perspectives, the other one is to use the Real Option theory to study the lagging investment problem of the big unit. Through an illustrative...
Rolls-Royce fuel cell systems is developing megawatt scale power systems based on solid oxide fuel cell technology. The hybrid design promises to meet challenging energy efficiency, cost and performance targets in a grid friendly fashion. Analysis and testing to date indicate that those targets can be met and enable a wealth of fuel cell applications to meet customer and existing grid and modern grid...
